A central processing unit (CPU) generates, from original image data representing an image, a right eye image and a left eye image mutually having a parallax. The CPU also specifies the 3D transformation parameter depending on the indication by a user, and stores the specified 3D transformation parameter in storage device in association with original image data.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An image processing apparatus comprising: a 3D transformation unit that comprises: a calculation unit that obtains a depth value for each pixel from original image data of an image based on a gradation of each pixel of the original image; an adjusting unit that adjusts the depth value obtained by the calculation unit by using a supplied 3D transformation parameter; and an image generating unit that generates a right eye image and a left eye image mutually having a parallax corresponding to the depth value obtained by the adjusting unit; a parameter specifying unit that specifies the 3D transformation parameter used for adjusting the depth value process depending on an indication by a user; and a control unit that stores the 3D transformation parameter specified by the parameter specifying unit in a storage device in association with the original image data.
2. The image processing apparatus of claim 1 , wherein the adjusting unit comprises a unit that adds a perspective depth value, which is a common value with regard to all pixels, to the depth value for each pixel, and the 3D transformation parameter specified by the parameter specifying unit includes the perspective depth value.
3. The image processing apparatus of claim 1 , wherein the adjusting unit comprises a unit that revises the depth value for each pixel into an average depth value of the depth values of pixels in an area including each pixel, and the 3D transformation parameter specified by the parameter specifying unit includes a value denoting a dimension of the area.
4. The image processing apparatus of claim 1 , wherein the adjusting unit comprises a unit that approximates the depth value for each pixel into one of a plurality of discrete values, and the 3D transformation parameter specified by the parameter specifying unit includes a value used for specifying a round-off value denoting a distance between the discrete values.
5. The image processing apparatus of claim 4 , wherein the value used for specifying the round-off value is an object depth value denoting a number of the discrete values.
6. The image processing apparatus of claim 1 , wherein the adjusting unit comprises a unit that adjusts the depth value for each pixel to a value within a prescribed range, and the 3D transformation parameter specified by the parameter specifying unit includes at least one of an upper limit and a lower limit of the prescribed range.
7. The image processing apparatus of claim 1 , wherein the control unit stores a plurality of sets of the original image data each of which is data of an image constituting a moving picture in the storage device, and the 3D transformation unit executes the 3D transformation process with regard to each of the plurality of sets of the original image data in real time using the 3D transformation parameter stored in the storage device in association with the original image data.
8. The image processing apparatus of claim 1 , the 3D transformation parameter specified by the parameter specifying unit including a parameter, the parameter being shared by all of the pixels of one or plural original image data.
9. An image processing apparatus comprising: a 3D transformation unit that comprises: a calculation unit that obtains a depth value for each pixel from original image data of an image based on a gradation of each pixel of the original image; an adjusting unit that adjusts the depth value obtained by the calculation unit by using a supplied 3D transformation parameter; and an image generating unit that generates a right eye image and a left eye image mutually having a parallax corresponding to the depth value obtained by the adjusting unit; a capture unit that captures an original image data of an image picked up by an image pickup device for picking up an image of an object and an image pickup condition under which the image is picked up; a parameter specifying unit that specifies the 3D transformation parameter to be used for adjusting the depth value process based on the image pickup condition captured by the capture unit; and a control unit that stores the 3D transformation parameter specified by the parameter specifying unit in a storage device in association with the original image data captured by the capture unit.
10. The image processing apparatus of claim 9 , the image pickup condition including various factors for regulating an amount of light under which the image is picked up, the image pickup condition under which the image is picked up being associated with the corresponding original image data of the image picked up.
11. A storage medium readable by a computer, the storage medium storing a program for making a computer function as: a 3D transformation unit that comprises: a calculation unit that obtains a depth value for each pixel from original image data of an image based on a gradation of each pixel of the original image; an adjusting unit that adjusts the depth value obtained by the calculation unit by using a supplied 3D transformation parameter; and an image generating unit that generates a right eye image and a left eye image mutually having a parallax corresponding to the depth value obtained by the adjusting unit; a parameter specifying unit that specifies the 3D transformation parameter used for adjusting the depth value process depending on an indication by a user; and a control unit that stores the 3D transformation parameter specified by the parameter specifying unit in a storage device in association with the original image data.
12. A storage medium readable by a computer, the storage medium storing a program for making a computer function as: a 3D transformation unit that comprises: a calculation unit that obtains a depth value for each pixel from original image data of an image based on a gradation of each pixel of the original image; an adjusting unit that adjusts the depth value obtained by the calculation unit by using a supplied 3D transformation parameter; and an image generating unit that generates a right eye image and a left eye image mutually having a parallax corresponding to the depth value obtained by the adjusting unit; a capture unit that captures an original image data of an image picked up by an image pickup device for picking up an image of an object and an image pickup condition under which the image is picked up; a parameter specifying unit that specifies the 3D transformation parameter to be used for adjusting the depth value process based on the image pickup condition captured by the capture unit; and a control unit that stores the 3D transformation parameter specified by the parameter specifying unit in a storage device in association with the original image data captured by the capture unit.
